Underwater photographer of the year 2020 and wide angle category winner: Frozen Mobile Home by Greg Lecoeur (France) in the Antarctic peninsula, Antarctica. Crabeater seals swim around an iceberg. These massive and mysterious habitats are dynamic kingdoms that support marine life. As they swing and rotate slowly through polar currents, icebergs fertilise the oceans by carrying nutrients from land that spark blooms of phytoplankton, fundamental to the carbon cycle.

Blizzard in the High Peak, Derbyshire, by John Finney: “After a difficult journey in the snow, I made my way from Mam Tor down onto the Great Ridge. As the clouds got darker, I placed the tripod and camera at just the right angle to avoid snow getting onto the lens, and used a flash gun and a relatively slow shutter speed to highlight the fast motion of the blizzard”. Classic view, adult class – winner. (Photo by John Finney/Landscape Photographer of the Year)
